Chapter 6
Genjutsu: False Surroundings Technique is a basic C-rank genjutsu that overlays everything the target sees with a layer of illusion, making them believe they see something entirely different. This technique is not harmful and is used purely to mislead the enemy visually, making it easy to break. However, it can be cast over a large area, affecting multiple targets simultaneously.
Genjutsu: Hell Viewing Technique is even more superficial, a D-rank ninjutsu. Everyone harbors fears; as the saying goes, "The more you fear something, the more likely it is to appear." The Hell Viewing Technique manifests the target's inner fears, making them seem real to shake their morale.
These two genjutsu, a C-rank and a D-rank, inspired Neiki to develop his S-rank genjutsu, The Abyss of Deception Technique.
Neiki's prowess in genjutsu is above average at best. Still, his analytical ability allows him to excel in developing and learning genjutsu at a speed even the genius Uchiha Itachi cannot match.
The Abyss of Deception Technique combines the characteristics of the two basic genjutsu mentioned above—non-lethal and primarily supportive. Its sole purpose is to "embellish" the reality perceived by all living beings within its range.
This "embellishment" effect, however, is quite astonishing.
Before targeting the Hyuga central family, Neiki tested his technique against genjutsu experts in Konoha, such as Uchiha Itachi and Kurenai Yuhi. When they could not even see through The Abyss of Deception Technique, Neiki knew he had succeeded.
The Abyss of Deception Technique alters everything seen, heard, and felt within its range to align with the victim's thought patterns, similar to how the Hell Viewing Technique projects the victim's fears. The Abyss of Deception Technique makes things appear as they "should be" in the victim's mind.
The technique’s strength lies in making objective reality conform to the subject’s subjective thoughts, making it extremely difficult to detect.
